A group is calling on Android and Microsoft to release an update that automatically makes phone screens go blank when driving.

They've written to the technology giants to introduce technology to prevent distractions when driving - potentially cutting the number of accidents.

The letter comes ahead of the expected release of iOS 11 which will include a do not disturb while driving mode that detects when someone is driving and turns off calls, text messages and notifications.

Brake and the RAC’s Be Phone Smart campaign, together with Brighton and Hove City Council, the Parliamentary Advisory Council on Transport Safety, RED Driving School, Road Safety GB and RoadPeace have applauded the new iPhone feature.
